 28.Xr honk 1 .
 29.Ss Setup
 30.Pp
 31Set up a TLS reverse proxy.
 32.Nm
 33can listen on TCP or unix sockets, but will not terminate TLS.
 34https is a required component for federation.
 35Also, http signature verification requires accurate time keeping.
 36.Pp
 37Make sure to pass the Host header, if necessary (as for nginx).
 38.Bd -literal -offset indent
 39proxy_set_header Host $http_host;
 40.Ed

 43.Nm
 44requires a go compiler 1.16 and libsqlite.
 45On
 46.Ox
 47this is the go and sqlite3 packages.
 48Other platforms may require additional development libraries or headers
 49to be installed.
 50Run make.
 51Please be patient.
 52Even on fast machines, building from source can take several seconds.
 53.Ss Options

 55.Nm
 56looks for data.

 85Set all three logs.
 86.El
 87.Ss Init
 88Run the
 89.Ic init
 90command.
 91This will create the database and ask four questions, as well as creating
 92the initial user.
 93See below about importing existing data.
 94.Ss Operation
 95Run honk.
 96.Ss Customization
 97The funzone contains fun flair that users may add to posts and profiles.
 98Add custom memes (stickers) to the
 99.Pa memes
100data directory.
101Image and video files are supported.
102Add custom emus (emoji) to the
103.Pa emus
104data directory.
105PNG and GIF files are supported.
106.Pp
107Site CSS may be overridden by creating a
108.Pa views/local.css
109file in the data directory.
110Site JS may similarly be included by creating
111.Pa views/local.js .
112A restart is required after changes.
113A site icon.png and favicon.ico will be served from the views directory
114in the data directory, if present.

133New users can be added with the

150.Ss Maintenance
151The database may grow large over time.
152The
153.Ic cleanup Op Ar days
154command exists to purge old external data, by default 30 days.
155This removes unreferenced, unsaved posts and attachments.
156It does not remove any original content.
157This will not immediately reduce the size of the database, but frees space
158for future use.
159A vacuum may be performed manually if necessary, but will require more time
160and additional disk space.
161.Pp
162Backups may be performed by running
163.Ic backup dirname .
164Backups only include the minimal necessary information, such as user posts
165and follower information, but not external posts.
166.Pp
167Sometimes servers simply disappear, resulting in many errors trying to deliver
168undeliverable messages.
169Running
170.Ic unplug Ar hostname
171will delete all subscriptions and pending deliveries.
172.Ss Upgrade
173Stop the old honk process.
174Backup the database.
175Perform the upgrade with the
176.Ic upgrade
177command.

180The current version of the honk binary may be printed with the
181.Ic version
182command.
183.Ss Security

185is not currently hardened against SSRF, server side request forgery.
186Be mindful of what other services may be exposed via localhost or the
187local network.
188.Ss Development
189Development mode may be enabled or disabled by running
190.Ic devel Ar on|off .
191In devel mode, secure cookies are disabled, TLS certs are not verified,
192and templates are reloaded every request.
193.Ss Import
194Data may be imported and converted from other services using the
195.Ic import
196command.
197Currently supports Mastodon, Twitter, and Instagram exported data.
198Posts are imported and backdated to appear as old honks.
199The Mastodon following list is imported, but must be refollowed.
200.Pp
201To prepare a Mastodon data archive, extract the archive-longhash.tar.gz file.
202.Dl ./honk import username mastodon source-directory
203.Pp
204To prepare a Twitter data archive, extract the twitter-longhash.zip file.
205After unzipping the data archive, navigate to the tweet_media directory
206and unzip any zip files contained within.
207.Dl ./honk import username twitter source-directory
208.Pp
209To prepare an Instagram data archive, extract the igusername.zip file.
210.Dl ./honk import username instagram source-directory
211.Ss Advanced Options
212Advanced configuration values may be set by running the
213.Ic setconfig Ar key value
214command.
215For example, to increase the fast timeout value from 5 seconds to 10:
216.Dl ./honk setconfig fasttimeout 10
217.Pp
218To support separate mentions without a subdomain,
219e.g. @user@example.com and https://honk.example.com/u/user,
220set config key 'masqname' to 'example.com'.
221Route
222.Pa /.well-known/webfinger
223from the top domain to honk.
224.Pp
225Custom URL seperators (not "u" and "h") may be specified by adding
226"usersep" and "honksep" options to the config table.
227e.g. example.com/users/username/honk/somehonk instead of
228example.com/u/username/h/somehonk.
229.Sh FILES
230.Nm
231files are split between the data directory and the view directory.
